Tim, would love to get it. But after reading the DIY, it's abit on the too hard basket for me. Also read that LCI subs are 2ohm vs the amp 4ohm which will put the stress on the amp.

If anyone knows where I can get this installed for a slab, this be gone already too!

Hello Rayz, just a technical correction for you on your post- the LCI subs are NOT 2ohm, the basic kit are 4ohm and therefore perfectly matched to the amp- this is why BMW released this kit- to update the basic stereo package ("stereo package"). I assume you read somewhere that all Logic7 subs are 2ohm, which they are, and incorrectly connected this to LCI for some reason. Note pre and post LCI audio systems are identicle from a hardware point of view.

Also on the DIY path- each to their own, I find this upgrade very simple indeed, as have many others (which convinced me to do an audio upgrade in the first place) so it really depends on whether you can follow instructions or not .
